Dicke transition in open many-body systems determined by fluctuation effects
Alla V. Bezvershenko, Catalin-Mihai Halati, Ameneh Sheikhan +2
In recent years, one important experimental achievement was the strong coupling of quantum matter and quantum light. Realizations reach from ultracold atomic gases in high-finesse…
Theoretical methods to treat a single dissipative bosonic mode coupled globally to an interacting many body system
Catalin-Mihai Halati, Ameneh Sheikhan, Corinna Kollath
We present two approaches capable of describing the dynamics of an interacting many body system on a lattice coupled globally to a dissipative bosonic mode. Physical realizations a…
Numerical evaluation of two-time correlation functions in open quantum systems with matrix product state methods: a comparison
Stefan Wolff, Ameneh Sheikhan, Corinna Kollath
We compare the efficiency of different matrix product state (MPS) based methods for the calculation of two-time correlation functions in open quantum systems. The methods are the p…
